Additional information

In accordance to REACH Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7C (v2.0, Nov. 2014, p.146), two long-term studies have been conducted as undecylenic acid falls within the soil hazard category 2 (very toxic to aquatic life). The performed studies are in accordance with those recommended in the guidance (OECD 222 and OECD 216). The two studies are long-term tests. A PNEC has been derived using a NOEC of 3.2 mg/soil dry weight and an assessment factor of 50, in accordance with ECHA's Guidance Chapter R.10 (May 2008).
